MCHINE'FOR MOSTENING AND COOLING FABRICS.

`Application :Med December 16, 1927, Serial No. 246,528, and in GermanyNovember 10, 1926.'

With the finishing of fabrics the serious inconvenience is encounteredthat the fabric after the drying in hot air or on heated drums or afterthe hot pressing has a hard, rough and dry unfinished touch as thefabric contains too'little moistness and natural heat.

By the machine for moistening and cooling fabrics according to theinvention, owing to the combination of two sets each of three superposedcylinders, the fabric can be moistened on one side or on both -sidesdirectly or indirectly or directly and indirectly in one operation thetwo sides of the fabric being moistened to the same degree or todifferent degrees. The guide rollers for the fabric are arranged inproximity to the point at which the lower cylinder touches theintermediate cylinder so that this intermediate 20 cylinder can grip thelargest'possible portion of the dry and hot fabric.

' The machine according to the invention is shown in vertical section,partly in elevation in the only figure of the accompanying drawing.

In the frame A of the machine two sets, cach of three rotatablecylinders, are arranged theone above the other. The intermediatecylinders I), b1 of the two sets are mounted in stationar bearings, thelower cylinders a, a1 being Joux-nailed' in bearings z', 1.which, bymeans of counter-weighted levers e, e1 can be pressed more or lessstrong- 1y against the cylinders I), b1. The cylinders a and a1 b and b1are preferabl covered with cloth. The cylinders a, a1 dip lnto watercontained in vessels d, d1 and transfer moistness to the cylinders b,b1. The pressurecylinders c, c1 mounted above the intermediate cylindersb, b1 canbe pressed more or less strongly against the cylinders b, b1 bythe action of adjustable counterweight levers f, f,-acting,upon thebearings vZ, Z1 of said cylinders c, o1. In proximity to the points ofcontact between the lower cylinders a and a1 and the intermediatecylinders b, b1 guide rollers 7c, 'k1 are arranged at the right and leftover which the fabric G is guided. On the axle of the cylinder b abelt-pulley 'n and possesses un- L a sprocket wheel o transmit rotatingmove- -moistness and duration of the cooling. The

drawing shows the case when the fabric has to be moistened on both sidesand indirectly and cooled as much as possible. The lfabric G,passing'over the guide-bars m and over the first guide-roller c, isconducted first (indicated 'in dash-lines), over theV cylinder b andthen" over the opposite guide-roller le so that one side of the fabricis moistened and cooled, whereupon the fabric is conducted a overlcylinder b1 to` the second-guide-roller k1 to pass over the oppositeguide roller :1 after this side of the fabric has been moistened to befurther conveyed in the direction of the arrow. 4 n v During the travelof the fabric the pressure cylinders c, e1 have pressed the desireddegree ofmoistness into the fabric. When only one side of the fabrichasl to be moistened, the fabric has to be conducted only over the lowerdipping cylinder a, whereby the corresponding side of the fabric ismoistened directly.

When the fabric has to be moistened directly on both sides, it isconducted over the lower dipping cylinder a and thence over the upperdipping cylinder a1. i

When the one side of the fabric has to be moistened directly and theother side. of the same has tor be moistened indirectly, the fabric hasto be conducted over the lower dipping-cylinder a and then over theupper intermediate cylinder b.

I claim y 1. A machine for moistening and cooling fabrics, comprising incombination two sets each of three cylinders, the one set of cylindersbeing arranged above the other set, and means for guiding the fabric sothat itis moistened in one operation as desired on one side or on twosides directly or indirectly or `directly and indirectly the degree ofmoistcylinder that the fabric is guided over the largest possiblecircumference of said intermediate cylinder the dry and hot fabric beingthereby moistened and cooledv to the maximum degree on both sides.

In ytestimony whereof I aiix my signature.

PETER WILHELM CSTERS.
